Product Description:

1,Cast Iron Manhole Cover Description :

manhole cover is a removable plate forming the lid over the opening of a manhole, to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.

Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people not having suitable tools to remove them.

A manhole cover sits on metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.


2,Main Features of the Ductile Iron Manhole Cover:

·High endurance

·High Strength

·Pressure Resistence



·Good visual effect

We have organized several common questions for our clientsmay help you sincerely

Q. Can I fit a square manhole cover into a round chamber?

A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers. 

Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why?

A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this.


Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?

A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.


Q. The project I’m working on requires a manhole cover with a quality finish, what’s available?

A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.


Q. Odours are coming through where I have installed my manhole cover, why?

A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.


Q. I need access through my manhole cover on a regular basis, is this possible?

A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.

Q:Alternative Metal bands?
I enjoy every sub-genre of Metal. Black Metal, Prog Metal, Tech Death, Thrash Metal, Power Metal, Folk Metal, Metalcore, you name it. I enjoy Hair Metal. My favorite Hair Metal bands include, but are not limited to, Guns N Roses, Mr. Big, Quiet Riot, Twisted Sister, Motley Crue, Ratt, Skid Row, Europe, and old Def Leppard. I think the main reason that most metalheads dislike Hair Metal is because it's a lot less heavy than other Metal and gets more attention than it deserves. I can't say I disagree, but personally I enjoy Hair Metal because it's catchy, upbeat, and requires talent to play (listen to Mr. Big if you don't believe me. You can't deny that Mr. Big is awesome).
Q:Recommend me some metal songs?

Q:Metal Chat?
pee yew
Q:Are metals crystalline?
Pretty sure metal is more head-banging. Take 80's ROCK for example. How many of those songs were head-banging like some Nickleback songs can be? Almost none. So metal is hardcore rock or rock is a soft metal
Q:Metal will never die out?
Metals are metallically bonded. this means there is a lattice of metal cations surrounded by delocalized electrons. This means that no electron is bonded to any specific ion in the metal lattice. (these ions are nuclei and inner shell electrons). this means that electrons are less tightly bound to the structure of the metal. this is why the photoelectric effect can occur (where light frees electrons from a metal surface completely).
Q:Stupid Metal subgenres!?
Symphonic metal is metal with orchestral instruments, such as violins and cellos. Also, usually an operatic singer Melodic metal is basically traditional metal Melodic death metal is traditional metal with death metal vocals Symphonic death metal is symphonic metal, but instead of operatic vocals, you have death metal vocals
Q:nonmetals vs metals?
Nu metal didn't bother me that much. It really just faded out and most of the nu metal bands just because alternative rock bands (Disturbed, Slipknot, ect). I hate hair metal and this new metalcore/deathcore bullshit the most. The worst is hearing people call deathcore and metalcore Death metal thinking they're the BR()()TAList kids ever.
Q:What exactly is the definition of Death Metal?
Basically, metal that was formed to bridge progresstive rock with metal, stealing the traits of both. It is more deatiled than ordinary metal, with odd time signatures that provide a unique effect. Read the article:
Q:Can the sun burn metal?
the metal gear series started all the way back on a little known system called the MSX here are a couple of links that give the game history and even a fictional timeline of what supposedly was going on in the world.
Q:Please introduce me to some metal.?
Salts are never metals. It is a compound. The ammonium ion is acidic, and the sulphate ion is weakly basic. Overall, ammonium sulphate is acidic, because ammonium is more acidic than sulphate is basic.
